CrossRef, a publisher collaborative that enables researchers to navigate online journals via DOI-based citation links, announced the launch of version 2.0 of its metadata database resolution service as well as an expansion of its publisher and affiliate memberships.

Development of the new resolution system began last year, when CrossRef joined forces with Atypon Systems. Because of the offering's robust "fuzzy" logic, there has reportedly been a significant increase in positive query results. This second-generation system uses a scalable architecture and the latest Web technologies, which result in more resolved queries and expanded reference content. Version 2.0 also supports the new CrossRef XML Deposit Schema, which provides a more robust vocabulary for journal metadata and conference proceedings. In addition, the new version now allows reference material to be deposited. Members will have Web access to a complete set of statistics and reports that detail their deposit and query activity. The extendable platform readily allows the addition of new features and services.

With the additions to CrossRef's membership base, the organization now has 152 publisher members whose content represents more than 6,400 journals and almost 5 million article records. Key expansion developments include the following:

The library affiliate program has grown to 49 with the recent addition of NIH.

CrossRef signed a linking-solutions partner agreement with Fretwell-Downing. The company will integrate CrossRef into its Z PORTAL product offering for libraries. This collaboration will automatically build links between citation information and digital content.

ProQuest has committed to support linking to full text via CrossRef and will be beta-testing dynamic retrievals using CrossRef's new system.

Project Muse, which offers subscription access to the full text of more than 200 scholarly journals in the humanities and social sciences, announced plans to actively participate in CrossRef beginning next year.
